[1] This application is based on and claims the priority of Chinese application No. 201710198859.1, filed March 29, 2017, the entire contents of which are incorporated herein by reference.

Technology area

[2] This application relates to the field of blockchain technologies and information processing technologies and, in particular, to methods and devices for processing transactions based on blockchain.

Prior art

[3] With advances in information technology, blockchain technology has gained widespread attention due to the benefits of openness, immutability and decentralization. In applications, blockchain technology is commonly used to store transaction information generated in transaction processes. Moreover, the emergence of smart contracts further expands the scope of transactions for blockchains.

[4] A smart contract is usually a segment of codes stored in the blockchain (or a blockchain node in the blockchain network) that provides the conditions for the execution of a smart contract and the logic for processing a transaction, namely, provides the conditions to activate a smart contract, and then, how to handle transaction processing requests received after the smart contract is activated.

[5] For example, in the case of a transfer transaction, when user A initiates a transfer processing request, the blockchain node determines whether the transfer parameters contained in the transfer processing request satisfy the execution conditions of the smart contract corresponding to the transfer transaction upon receiving the transfer processing request. If so, the blockchain node executes the transfer processing request. Here, the execution conditions of the smart contract corresponding to the transfer transaction can be interpreted as whether the balance in the account of user A satisfies the required transfer amount, and the like. A smart contract is a digital obligation defining rights and obligations voluntarily agreed by the parties to the contract.

[6] In reality, however, there is a type of administrative intervention in the ad hoc transaction category. For example, when a user performs illegal activities, an injunction can be enforced to freeze the user's account. However, this operational action conflicts with smart contracts in existing blockchains and cannot be performed.

[7] Therefore, there is a need for a blockchain-based transaction processing method that enables ad hoc transactions similar to administrative intervention on the blockchain.

Brief description of the essence of the invention

[8] Embodiments of the present application provide blockchain-based transaction processing methods and devices to provide ad-hoc transactions like administrative intervention on the blockchain, thus overcoming the existing problem.

[9] In accordance with one aspect, a method for processing a blockchain-based transaction may comprise: in response to a designated account registered through the application client, generating, in accordance with the entered transaction information and the configured transaction content, an operating instruction containing the information accounts for the transaction and the contents of the transaction; and sending an operating instruction to a node in the blockchain network, causing the node in the blockchain network to invoke a smart contract corresponding to the designated account after receiving the operating instruction, and execute the operation according to the transaction content on another account corresponding to the account information for the transaction.

[10] In accordance with another aspect, a method for processing a blockchain-based transaction implemented by a node in a blockchain network may comprise: receiving an operating instruction containing account information for a transaction and the contents of the transaction; in response to the determination that the account issuing the transaction instruction matches the account issuing the transaction instruction, defining a smart contract corresponding to the account issuing the transaction instruction; and on the basis of a smart contract, the execution of the transaction in accordance with the content of the transaction in another account corresponding to the account information for the transaction.

[11] In accordance with another aspect, a blockchain-based transaction processor may comprise a processor and non-temporary computer-readable storage medium storing instructions that, when executed by the processor, cause the device to perform the method. The method may comprise: generating, in response to a designated account registered through the application client and in accordance with the entered transaction account information and configured transaction content, an operating instruction containing transaction account information and transaction content; and sending an operating instruction to a node in the blockchain network, causing the node in the blockchain network to invoke a smart contract corresponding to the designated account after receiving the operating instruction and execute the operation according to the transaction content on another account corresponding to the account information for the transaction.

[12] In accordance with another aspect, a blockchain-based transaction processor may comprise a processor and non-temporary computer-readable storage medium storing instructions that, when executed by the processor, cause the device to perform the method. The method may comprise: receiving an operating instruction containing account information for the transaction and the contents of the transaction; in response to the determination that the account issuing the transaction instruction matches the account issuing the transaction instruction, defining a smart contract corresponding to the account issuing the transaction instruction; and execution, on the basis of a smart contract, of the transaction in accordance with the content of the transaction in another account corresponding to the account information for the transaction.

[13] At least one technical solution used by the above embodiments of the present disclosure can achieve the following beneficial results.

[14] In some embodiments, corresponding smart contracts are created for various administrative oversight accounts (also referred to as designated accounts). Thus, upon receipt of an operating instruction sent from a designated account, a node on the blockchain network can invoke the appropriate smart contract upon determining that the operating instruction has been legitimately issued in order to execute the corresponding transactions on the account corresponding to the account information for the transaction, thus providing oversight. over accounts in the blockchain and allows special transactions to be carried out similar to administrative intervention in the blockchain.

Detailed description

[20] The technical solutions of the present application will be clearly and fully described below with reference to various embodiments of the present disclosure and the corresponding drawings. The described embodiments are exemplary only. All other embodiments available to those skilled in the art without creative effort and based on the embodiments of the present disclosure are to be included within the scope of the present disclosure.

[21] Technical solutions in accordance with the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[22] FIG. 1 illustrates a method for processing a blockchain-based transaction in accordance with an embodiment of the present disclosure, and a method for processing a transaction may include the following steps. One or more steps such as S101 may be optional.

[23] S101: providing an application client for a designated account.

[24] A designated account in embodiments of the present disclosure may comprise a dedicated account with administrative oversight capabilities. To ensure the security of the designated account, a dedicated application client (eg, software application) may be provided for the designated account.

[25] The designated account can use the same application client or different application clients for different administrative oversight capabilities. In other words, the application client can be provided to support the use of designated accounts with a variety of administrative oversight capabilities on it, and different designated accounts can invoke the corresponding functions according to their own needs. Moreover, different clients of the application can be provided according to the needs of the designated accounts, and each client of the application is exclusively used for the designated account, which is not limited herein.

[26] S102: in response to the designated account registered via the application client, generating, in accordance with the entered transaction account information and the configured transaction content, an operating instruction containing transaction account information and transaction content.

[27] In one embodiment, when the administrative supervisor needs to perform administrative supervision on one account, he / she needs to complete the login (registration) operation through the application client in step S101, namely, by entering the login name and password of the designated account, appropriate authorization of administrative supervision by the official representative of administrative supervision on the application client registration interface. At this point, the application client can verify the entered account login name and password and allow the registration to complete when the verification is complete. Thus, it can ensure the security of the implementation of administrative oversight in the Internet environment.

[28] When the designated account is registered through the application client, the administrative oversight officer can enter the account information when administrative oversight is needed (hereinafter, the account information is referred to as account information for the transaction) and the transaction content on the operational interface provided by the application client. After receiving the entered transaction account information and the configured transaction content, the application client may generate an operation instruction containing the transaction account information and transaction content in accordance with the entered transaction account information and the configured transaction content.

[29] In one embodiment, when generating the operating instruction, the method may further comprise: using an algorithm to determine the summary of the operating instruction, and using the private key in the public-private key pair corresponding to the assigned account to encrypt the summary to obtain an encrypted summary ...

[30] The algorithm herein may be a hash algorithm and may also be other algorithms that are not limited herein.

[31] In some embodiments, a set of public-private keys is defined for different designated accounts. Namely, different designated accounts have different corresponding public-private key pairs, which can effectively prevent leakage of public-private key pairs.

[32] S103: Sending an operating instruction to a node on the blockchain network, prompting the node on the blockchain network to call the smart contract corresponding to the assigned account after receiving the operating instruction, and execute the operation according to the transaction content on the other account corresponding to the account information to conduct operations.

[33] In one embodiment, if the encryption processing is performed on the operating instruction, the encrypted digest and the operating instruction need to be sent to a node in the blockchain when executing S103.

[34] In one embodiment, the method further comprises: configuring smart contracts for different assigned accounts according to attributes of the assigned accounts, wherein smart contracts are used to execute transactions in accordance with operational instructions sent by the assigned accounts and different assigned accounts have various corresponding smart contracts.

[35] Smart contracts represent an important content of transaction execution on the blockchain network. Smart contracts are created for different designated accounts in different embodiments of the present disclosure. Different smart contracts are created according to different attributes of the assigned accounts, for example, the characteristics of the transaction instructions sent. Launch conditions and transaction processing logic are prescribed in each smart contract. The transaction processing logic herein may be determined according to the transaction content of the operating instruction. The startup conditions in this document can be determined according to actual needs. For example, when an operating instruction is received, it is determined whether the current transaction is legal, expedient, or the like.

[36] In some embodiments, the smart contract is written into a block in the form of a smart contract address. When a node needs to invoke a smart contract, the node can retrieve the contents of the smart contract via the smart contract address.

[37] Here, in relation to the smart contract address, the smart contract can be stored in the node where the corresponding designated account is located, which also assigns the storage address for the smart contract. Alternatively, a third party device provides a storage address for the smart contract, which is not limited herein. There are many ways to implement in relation to the storage process of the aforementioned smart contract, the form of the smart contract when stored in the blockchain (is only the address of the smart contract stored).

[38] FIG. 2 illustrates a method for processing a blockchain-based transaction in accordance with an embodiment of the present disclosure, and the method for processing a transaction may comprise the following steps. The method can be implemented through a node in a blockchain network.

[39] S201: receiving an operating instruction.

[40] Here, the operating instruction may contain account information for the transaction and the contents of the transaction.

[41] In one embodiment, all nodes in the blockchain can receive transaction data entered by a user and process the received transaction data, wherein the transaction data can be entered by the user through an account entered at the node's client, by the user through another client and sent to the node and etc. The specific way in which transaction data is sent or entered into a node is not limited in this disclosure. Then, the operating instruction received by the node in step S210 can also be processed as transaction data. This transaction data may differ from the transaction data described above, as this transaction data must be processed through a specific smart contract.

[42] Assuming that the operating instruction is processed as transaction data, there are many types of transaction data, and the contents of the operation contained in the operating instruction may be carried in different forms in the transaction data. For example, when the blockchain is a blockchain with coins (“coins”), the transaction data in the blockchain with coins may be transaction data corresponding to transactions, and therefore the contents of the transaction can be carried in the transaction notes of the transaction data; when the blockchain is a non-coin blockchain, the transaction data on the non-coin blockchain may correspond to the transaction data that is not related to transactions, such as transactions of storing registration information, identity verification, etc., and therefore there may not be strict specifications for specific the contents of the transaction data. As a result, the content of an operation can thus be treated directly as transaction data, which is not limited in the present disclosure.

[43] In some embodiments, a node on a blockchain may be a terminal installed with a blockchain client such as a cell phone, tablet computer, personal computer, and the like, or may be a multi-device system. In the present disclosure, a node may comprise a server, such as a server containing a single device, or a server system containing a plurality of devices.

[44] S202: In response to determining that the account issuing the transaction instruction matches the account issuing the transaction instruction, determining a smart contract corresponding to the account issuing the transaction instruction.

[45] In one embodiment, when the transaction instruction is received, the account issuing the transaction instruction is determined (the issuing account may here be interpreted as a designated account in S101), an algorithm (eg, a preselected or set algorithm) is used to determine the summary of the transaction instruction, and the public key in the public-private key pair corresponding to the issuing account is used to encrypt the digest to obtain the encrypted digest.

[46] The resulting encrypted bulletin is compared with the encrypted bulletin contained in the operating instructions to see if they are the same.

[47] If the received encrypted bulletin is the same as the encrypted bulletin contained in the transaction instruction, it is determined that the account sending the transaction instruction is the same as the account issuing the transaction instruction, indicating that the operating instructions received are legal.

[48] Here, the issuing account recorded in various embodiments may be an account held by a government agency or a trusted entity. Since the corresponding smart contracts are created for different designated accounts, this indicates that the operating instructions issued by the designated accounts are recognized. As a result, effective administrative supervision can be performed on all accounts in the blockchain network, and this type of supervision is limited, which will not restrict normal transactions on the blockchain network.

[49] In one embodiment, to ensure the validity of subsequent transactions, after the transaction instruction is received, a digital signature (eg, an encrypted summary) of the transaction instruction may additionally be used to perform identity verification (also referred to as signature verification) on the designated account that sends the transaction instruction to determine if the account sending the transaction instruction is a preset issuing account authorized to send the transaction instruction.

[50] When determining that the account issuing the transaction instruction is the same as the account issuing the transaction instruction, the smart contract corresponding to the account issuing the transaction instruction may be further determined in accordance with a predetermined mapping relationship between the issuing accounts and smart contracts.

[51] In one example, as shown in FIG. 1, smart contracts can be configured for different assigned accounts, and a mapping relationship can be created between assigned accounts and smart contracts:

Table 1

Designated Account Types (Issuing Account) Smart contract Activity content Judicial Supervision Account Smart contract 1 Freezing an account, unfreezing an account Security Authority Oversight Account Smart contract 2 Suspend, resume, close, open Administrative Body Supervision Account Smart contract 3 Mandatory translation ...... ...... ......

[52] In some embodiments, different transaction contents of the same designated account may be configured with corresponding smart contracts. With the judicial oversight account as an example, the corresponding smart contract can be configured for the freeze operation, and also the corresponding smart contract can be configured for the unfreeze operation. These two smart contracts may differ from smart contract 1 shown in Table 1.

[53] In one embodiment, the smart contract corresponding to the issuing account may be further determined in accordance with the relationship shown in Table 1.

[54] In one embodiment, moreover, different assigned accounts can be used to issue different operating instructions, and the operating instructions can include, but are not limited to: a freeze instruction, a defrost instruction, a pause instruction, a resume instruction, a close instruction, opening instruction and mandatory translation instruction.

[55] In one embodiment, moreover, the above-described various operating instructions with different functions may be presented, and the operating instructions all correspond to accounts corresponding to the account information for the transaction. As a result, operating instructions are required in some embodiments. In other words, the designated account has oversight power over all other accounts on the blockchain, and therefore the oversight power needs to be decentralized. Decentralizing the oversight power can not only prevent emergencies with one of the designated accounts (e.g., seizure by criminals) when all oversight power is lost, but it can also prevent the account user using the designated entity from abusing the power, etc. etc. Therefore, there may be a plurality of designated accounts authorized to send various operating instructions.

[56] In this way, the oversight power of the blockchain accounts can be decentralized so that the oversight power over the blockchain is not centralized in one designated account, and the effectiveness and reliability of oversight can be guaranteed. At the same time, it prevents the loss of all supervisory powers on the blockchain when one designated account is compromised.

[57] S203: based on a smart contract, executing a transaction according to the transaction content in another account corresponding to the account information for the transaction.

[58] In one embodiment of the present disclosure, when the transaction content satisfies the smart contract execution condition, the transaction may be executed on an account corresponding to the account information for the transaction in accordance with transaction processing logic corresponding to the transaction content contained in the smart contract.

[59] For different transaction contents, different transactions are executed on an account corresponding to the account information for the transaction. In some embodiments, the contents of the transactions will be described in detail below in terms of freezing an account, unfreezing an account, suspending an account, resuming an account, closing an account, opening an account, and mandatory account transfer as examples.

[60] If the content of the transaction is to freeze the account, the freeze operation is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the freeze of the account contained in the smart contract, the freeze operation is used to enforce stop the execution of transactions related to account information for the operation.

[61] In one example, when the operating instruction is a freeze instruction, the transaction parameters corresponding to the operating instruction may include: the freeze type and the address of the frozen account, wherein the freeze type can include that sales and purchases are prohibited for the frozen account, only sales are allowed for a frozen account, purchases are not allowed for a frozen account, etc. Therefore, when the freezing operation is executed on the account corresponding to the account information for the transaction, various freezing operations can be executed according to the freezing type.

[62] If the content of the transaction is to unfreeze an account, the unfreeze operation is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the unfreeze of the account contained in the smart contract, the unfreeze operation is used to prescribe resume execution of transactions related to account information for the transaction.

[63] In one embodiment, before executing a defrost operation on an account corresponding to the transaction account information, the method further comprises: determining whether the account corresponding to the transaction account information is frozen.

[64] When it is determined that the account corresponding to the transaction account information is frozen, the unfreezing operation is executed on the account corresponding to the transaction account information.

[65] If the content of the transaction is to suspend the account, the suspension operation is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the suspension of the account contained in the smart contract, the suspension operation is used to enforce the account corresponding to the account information for the transaction, stop the execution of transactions.

[66] In one example, when the operating instruction is a suspend instruction, the operation parameters corresponding to the operational instruction may include: a suspend parameter, wherein the suspend parameter may be a suspension time period for a suspended account, such as a suspension start time and a time the end of the suspension. When the suspension operation is executed on the account corresponding to the account information for the transaction, the time to execute the suspension on the account corresponding to the account information for the transaction can be determined in accordance with the suspension parameter, for example, stopping the execution of transactions when the suspension start time is reached; when the end time of the suspension is reached, automatic release of the suspended state, for example, resuming the execution of transactions.

[67] If the content of the transaction is to renew the account, the renewal operation is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the account renewal contained in the smart contract, the renewal operation is used to enforce the account corresponding to the account information for the transaction, resume the execution of transactions.

[68] In one embodiment, before executing a resume operation on an account corresponding to the transaction account information, the method further comprises: determining whether the account corresponding to the transaction account information is in a suspended state.

[69] When it is determined that the account corresponding to the transaction account information is in a suspended state, the resume operation is executed on the account corresponding to the transaction account information.

[70] In some embodiments, if a suspended account accepts a resume operation before the suspension end time is reached, it does not need to wait until the suspension end time is reached, but can directly resume execution of the received transaction instruction.

[71] If the content of the transaction is to close an account, the close transaction is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the account closure contained in the smart contract, the close transaction being used to instruct to stop the execution of transactions.

[72] In one example, when a close operation is executed on an account corresponding to the account information for the transaction, an account information queue corresponding to the account information for the transaction is determined and the suspension operation is sequentially executed on the account corresponding to each piece of account information in the account information queue ...

[73] If the content of the transaction is to open an account, the opening transaction is executed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the account opening contained in the smart contract, the opening transaction being used to resume execution of transactions.

[74] In one embodiment, a close transaction can be handled as a set of close transactions executed on all accounts. For example, the general account on which the closing operation is performed corresponds to a plurality of sub-accounts. When the closing operation is executed on the general account, it means that the suspension operation will be executed on a plurality of sub-accounts corresponding to the general account. In one embodiment, when a close operation is executed on a shared account, the bulk send function can be used to send a suspend instruction to sub-accounts managed by the shared account, which then implements the suspend operation on all sub-accounts, thereby achieving the result that all accounts in the blockchain are suspended at the same time, i.e., the result of the closure.

[75] The principle of opening is the same as the principle of closing, while the opening is the opposite of a closing situation, which will not be redescribed in this document.

[76] In one embodiment, moreover, different states may be set for accounts. When the account state is set as the open state, the account can execute transactions normally; when the account state is set to closed, the account stops executing transactions. Here, account states are managed through a closing instruction and an opening instruction. When a closure is required, the security authority administration account can send a close instruction to invoke the corresponding smart contract, so that the account states are adjusted to the closed state; when opening is required, the security authority administration account can send an open instruction to invoke the corresponding smart contract, so that the account states are adjusted to the open state, thereby achieving the result to control the opening and closing of the blockchain.

[77] In one embodiment, furthermore, script (script) codes may be compiled on a node registered with a designated account with respect to sending a close instruction and an open instruction, so that the node automatically sends a close instruction and an open instruction to achieve an open control result and closing accounts.

[78] In one example, the script codes can be JavaScript or the like, and account information (eg, account IDs) for accounts on the blockchain can be stored in script codes or a node. When the designated account needs to send a close instruction, the script codes can be triggered so that the script codes automatically execute, according to the stored account information for the accounts, the suspension operation on the accounts, respectively, in order to achieve the result that all accounts in the blockchain are suspended (i.e. that is, the result of the closure).

[79] If the content of the transaction is a mandatory transfer, the mandatory transfer operation is performed on the account corresponding to the account information for the transaction, in accordance with the transaction processing logic corresponding to the mandatory transfer contained in the smart contract, the mandatory transfer operation is used for the mandatory transfer of the specified the amount of resources from the account corresponding to the account information for the transaction, according to the content of the transaction.

[80] In one example, when the transaction instruction is a mandatory transfer instruction, the transaction parameters corresponding to the transaction instruction may include: account address to transfer to account (accrual accounts), account address to transfer from account (debited account), and limit of the amount (amount) of the obligatory transfer. When a mandatory transfer transaction is executed on an account matching the account information for the transaction, the transaction can be initiated according to the accrued account address, debited account address, and the mandatory transfer amount limit, by obligatory transferring the limit from the debited account to the accrued account.

[81] Therefore, using the method described above, the designated account on the blockchain can supervise all accounts through specific smart contracts. Since the specific contents of smart contracts can be compiled by employees in accordance with the need for practical applications, the assigned account is provided with the ability to execute transactions on all accounts in the blockchain, thereby supervising the accounts in the blockchain. Since the operating instruction can be stored in the blockchain block, the operating instruction is immutable and can be requested. Namely, the operating instruction is certified so that the account activities of all designated entities are open and transparent, which makes it easier to identify acts that abuse the authority, and therefore improves the reliability of the accounts of all designated entities. Moreover, decentralizing the authority to supervise the accounts of different designated entities can further avoid the possibility that the accounts on the blockchain are affected by the fact that they contain the account of the designated entity. By avoiding the normal operations of all accounts on the blockchain, the method according to various embodiments can add supervisory authority to all accounts, which solves the problem of the difficulty of supervising according to the existing blockchain technology.

[82] With the solutions in accordance with the embodiments of the present disclosure, corresponding smart contracts are created for different administrative supervisory accounts (also called designated accounts). Thus, after receiving an operating instruction sent from a designated account, a node on the blockchain network can invoke the appropriate smart contract when determining that the operating instruction has been issued lawfully in order to execute the corresponding transactions on the account corresponding to the account information for the transaction, which achieves the goal of supervision over accounts in the blockchain and solves the problem of processing special transactions similar to administrative intervention in the blockchain.

[83] Based on the blockchain-based transaction processing method shown in FIG. 1, the disclosure accordingly provides a block diagram of a blockchain-based transaction processing apparatus as shown in FIG. 3.

[85] The provisioning module 301 optionally provides an application client for a designated account.

[86] The generating unit 302 generates, in response to the designated account registered through the application client and in accordance with the entered transaction account information and transaction content, an operating instruction containing transaction account information and transaction content.

[87] The sending module 303 sends an operation instruction to a node on the blockchain network, prompting the node on the blockchain network to invoke the smart contract corresponding to the assigned account after receiving the operation instruction and execute the operation in accordance with the transaction content on another account corresponding to the account information to conduct operations.

[88] In one embodiment, the transaction processor further comprises an encryption module 304.

[89] The encryption module 304 uses, when generating the operating instruction, an algorithm to determine the summary of the operating instruction, and uses the private key in the public-private key pair corresponding to the designated account to encrypt the summary to obtain the encrypted summary. Sending an operating instruction by the send module 303 to a node in the blockchain comprises sending an encrypted summary and an operating instruction to a node in the blockchain.

[90] In one embodiment, for different designated accounts, the corresponding public-private key pairs are different.

[114] In one example, a blockchain-based transaction processor as shown in FIG. 4 can be located at the node of the blockchain network. A node can contain a server, which is a single device or a system containing multiple devices. Alternatively, the node may comprise a terminal, such as a cell phone, tablet computer, personal computer, and the like. In accordance with one aspect of the present disclosure, modules 401-403 are functional software modules stored in memory, such as non-temporary and computer-readable memory. Apparatus 400 may include a processor for executing software functional modules 401-403 to perform relevant functions. In accordance with another aspect, modules 401-403 may be implemented in hardware, such as logic, programmed to perform functionality.

[115] In some embodiments, the transaction processor may be implemented in software or in hardware, which is not limited herein. Upon receipt of the operating instruction, the transaction processor can effectively determine whether the issuance of the operating instruction is legal.

[116] In the 1990s, improvements in technology could be distinguished as improvements in hardware (eg, improvements in circuit structure such as diode, transistor, switch, and the like) or improvements in software (improvements in process flow). Along with technological developments, however, many of the current process flow improvements can be understood as direct improvements to hardware circuitry structures. Designers can obtain an appropriate hardware diagram structure by programming the improved process flow into the hardware diagram. Therefore, an improvement in the flow of the method can be realized through the implementation of hardware. For example, a programmable logic device (PLD) (such as a programmable gate array (FPGA)) is an integrated circuit whose logic functions are defined by the user through device programming. The designer can program to “integrate” the digital system onto a single PLD element without asking the chip manufacturer to design and manufacture a custom IC chip. Nowadays, this type of programming is mainly implemented through “logic compiler” software rather than by hand-crafting IC chips. The logic compiler software is similar to the software compiler used to develop and write programs, while a specific programming language called the Hardware Description Language (HDL) is used to write the source code before compilation. There is not one but many HDL types such as ABEL (Advanced Boolean Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava , Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language). The most commonly used HDL includes VHDL (High Speed Integrated Circuit Hardware Description Language) and Verilog. A person skilled in the art should know how to obtain a hardware circuit in order to implement a logical flow of the method using the above HDLs to perform some logic programming on the flow of the method and program it into the IC.

[117] The controller can be implemented in any suitable way. For example, a controller may be implemented in the form of a microprocessor or processor, as well as a computer-readable medium that stores computer-readable program codes (such as software or firmware) capable of being executed by a (micro) processor, logic circuit, switch, ASIC ( ASIC), programmable logic controller and embedded microcontroller. Examples of controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the memory control logic. A person skilled in the art should also be aware that in addition to implementing the controller only by computer readable program codes, it is possible to perform logic programming in the steps of the method to allow the controller to implement the same functions in the form of a logic gateway, switch, ASIC, programmable logic controller, and built-in microcontroller. Therefore, such a controller can be understood as a piece of hardware, while devices contained therein and configured to perform various functions can also be understood as a structure within a piece of hardware. Alternatively, devices configured to perform various functions can be understood as both software modules for implementing the method and as a structure within a piece of hardware.
